Here is a Sanskrit shloka attibuted to Bhamini's Sabhatarangini:
न चोरहार्यं न च राजहार्यं न भ्रातृभाज्यं न च भारकारि।
व्यये कृते वर्धत एव नित्यम् विद्याधनं सर्वधनप्रधानं।।
It cannot be stolen by the thieves or the kings, nor can brothers divide it and it is burden less. Every time its is spent it grows. Knowledge is indeed the supreme wealth.
